Abstract :
A coating consisting of an ionic liquid (1,3-butylmethylimidazolium hexafluorophosphate[BMIM][PF6]) was deposited on silica gel as well as on a new polyvinylimidazolium phase and treated with atask specific onium salt (TSOS). The activity and stability of both immobilised Pd-species were studied and compared in Mizoroki-Heck cross coupling reactions.
